*Notice: Stresses above those listed under “Maximum Rat-

ings” may cause permanent damage to the device. This is a

stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

operational listings of this specification is not implied. Expo-

sure to maximum rating conditions for extended periods may

affect device reliability.

Note 1: The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the

input-referred trip points.

2: VHYST at different temperatures is estimated using VHYST (TA) = VHYST @ +25°C + (TA - 25°C) TC1 + (TA - 25°C)2 TC2.

3: Limit the output current to Absolute Maximum Rating of 50 mA.
